Sculptor Anthony Gormley “recently erected 30 nude sculptures around London to promote his current show at the Hayward Gallery. One such work was placed on the fly tower over at the National Theatre. This has caused problems. The fly tower is currently adorned in grass as part of an installation by the celebrated artists Heather Ackroyd and Dan Harvey.” The pair are reportedly quite displeased, but the theatre says that nothing could be done to avoid the double-booking.
